Application filed April 23,

-To all whom it may concern:

Be it linown that we, KNUD J. V. F REI- rAo, a subject of the King of Denmark. and HowAnn D. Amswon'rn, a citizen of the United States, both residents of the city and county of San Francisco and State of California, have invented a new and useful Pump Overflow-Pan, of which the following is a specification.

Our invention relates to overflow pans. and an object of the invention is to provide improved means on a pump for supporting a measuring or other receptacle below the discharge spout and for catching and returning to the supply reservoir any overhow from the receptacle and drippings from the spout.

The invention possesses other features of advantage, some of which, with the foregoing, will be set forthin the following description of the preferred form of our invention which is illustrated in the drawings accompanying and forming part of the specification. It is to be understood that we do not limit ourselves to the showing made by the said drawingsandulescription, as we may adopt variations of the preferred form within the scope of our invention as set forth in the claims.

Referring to the drawings:

Figure 1 is a side elevation of a pump equipped with the overflow pan of our invention, portions being broken away to dis close the structure. Fig. 2 is a plan view oi? the overflow pan. the pump parts being omitted. Fig. 3 is a vertical sectional view, the plane of section being indicated by the line 3-3 of Fig. 1.

The overflow pan of. our invention comprises .a hollow base 2, upon which the pump cylinder 3 is secured by means of tension rods 4, attached to the upper cylinder head 6 and threaded into the base after passing through the flange 7 of the lower head 8, which bears on the base. A nipple 9 threaded into the lower-end ot' the base provides means for mounting the pan and pump supported thereon upon the reservoir or barrel- .12, the lower end of the nipple being threaded 'into an aperture in the reservoir wall. The lower cylinder head 8 is provided with a hollow boss 13 in communication with the pump chamber and a pipe 14 threaded into this boss extends Specification of Letters Patent.

conjunction with a sloping bottom wall 19 so that a circular tray or pan of decreasing depth is formed about the open side of the base and extending outwardly therefrom. The bottom 19 slopes inwardly and downwardly irom thc rim 18 in that portion 19 remote from the opening of the pan into the base, but from about the center of the pan, the bottom slopes in a radial direction directly toward the aperture in the base so that a channel 20 is formed from the center of the pan into the hollow base, the portion 19 of the bottom sloping into the channel so that liquid falling anywhere on the pan runs into the channel and thence into the hollow base, and through the annular passage 21 into the barrel.

In order to provide a a measure or other receptacle placed on the pan, radial ribs 22 are disposed on the bottom portion 19, and a radial rib 23 disposed longitudinally in the channel. screen 9A for preventing foreign matter from passing from the channel into the hollow base is disposed at the inner end of the channel, being sprung between the shoulders 26 at the ends of the screen, and the end of the rib 23 on the opposite side and in the middle of the screen.

To claim:

level support for 1. ln combination with a pump, an overflow Jan eomirisim a hollow base ll)0l1 which the pump is mounted, a shallow traylikc receptacle extending from one side of saidbase, said side being apertured to provide a passage from said tray'likc receptacle into said base, the bottom of said tray-like receptacle being sloped toward said passage, ribs for supporting a measure disposed on said sloping bottom, and a screen disposed across said passage and held therein by one of said ribs.

2. In combination with a pump, an over flow pan comprising hollow base upon which the pump is mounted, a shallow traylike receptacle extending from one side of said base, and being formed with a chan-.

nel of decreasing depth extending from said base toward the center of'said tray-like receptacle, the side of said base being apertured to provide a passage fromsaid channel into said base, the bottom of said traylike receptacle being sloped toward said channel, and ribs having their upper-edges substantially in a horizontal plane disposed in said tray-like receptacle.

In testimony whereof, we have hereunto 15 set our hands at San Francisco, California. this 15th day of April, 1919.
